This fern with a sub-Atlantic-Mediterranean distribution is present in all regions of Southern Italy facing the Tyrrhenian Sea, in the Islands, and in Puglia on the Gargano Peninsula. It grows in grassy sites, especially on siliceous substrates, on acidic, fresh soils, from sea level to about 1000 m. It is a characteristic species of the Sardinian temporary ponds, but is rare, in the outer belt. The development of the prothallus (gametophyte) requires the presence of a symbiotic fungus, and the formation of a new sporophyte takes several years. The genus name derives from the Greek 'ophis' (snake) and 'glossa' (tongue), referring to the shape of the sporiferous spike; the species name refers to the ancient region of Lusitania, corresponding to modern Portugal. Sporulation period: August to December.

Italian name(s): Ofioglosso lusitanico (Italia)
